I have the Predator with the newest revision. I put the H2's on and adjusted the speedo with the Predator. Using my GPS it looks like the speedo is about 3 mph fast at all times. Anyone else have issues? Any suggestions on how to fix? I could adjust the tire size...but I wanted to figure out a good direction.
Thanks,
Anthony

I to have the Predator and you just have to play with the tire sizes. I have 295/70/17 Toyo's on and the tire size I found that worked ( after about 3 different tries) was 260/70/17.

I have found that 315/63R17 works perfectly according to my GPS for H2 rims/tires. I decided playing with the aspect ratio was easiest.
